Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →If HDR looks faded, too bright, or different from one app to another on your Mac, first check which display is affected and its selected preset. Then check HDR playback and battery settings, isolate app-specific previews, and—on supported XDR displays—look for Apple’s brightness-limited warning. An external display’s connection can also restrict its capabilities, but a cable change is not a universal fix for washed-out color.
First identify the display and where the problem appears
Note whether the affected screen is the Mac’s built-in display or an external monitor, and whether the appearance changes across the whole desktop or only in a particular app, video, or preview. The controls differ: Apple documents a High Dynamic Range control in Displays settings for supported third-party HDR10 displays; it is not a general HDR switch for a Mac’s built-in display. Apple’s HDR video instructions describe the supported external-display control.
Check the display preset or reference mode
Go to Apple menu > System Settings > Displays, select the affected display, and inspect its Preset menu. A preset can change color space, white point, gamma, and brightness together, so an unfamiliar mode may make the image look unexpectedly dim, bright, or unlike the rest of the system. Preset availability depends on the display and macOS version. Apple’s reference-mode guide explains the available modes and their intended workflows.
For normal home or office use, choose a general-use option rather than a production reference mode unless you have a specific color-managed workflow. Reference modes are designed for particular media and viewing environments; Apple cautions that using one with the wrong media or conditions can produce unsatisfactory results. Don’t create a custom mode as the first troubleshooting step.

Peak-brightness figures are not targets for diagnosing ordinary HDR appearance. For example, Apple lists up to 1,600 nits peak for the Apple XDR Display (P3-1600 nits) mode on supported MacBook Pro and Pro Display XDR configurations, and 1,000 nits full-screen sustained for the HDR Video (P3-ST 2084) mode on supported XDR displays. These are mode- and display-specific figures, not universal settings or thresholds. Apple’s mode descriptions give the corresponding conditions.
Check external HDR playback and battery optimization
For a supported external HDR10 display
Open Apple menu > System Settings > Displays, select the external display, and check whether High Dynamic Range is enabled. This control appears for supported third-party HDR10 monitors; the option and behavior depend on the Mac and display.

If HDR video changes on battery
If video looks like SDR only when the Mac is unplugged, connect the Mac to power and test again. Alternatively, check Battery settings for Optimize video streaming while on battery and turn it off to test. With that optimization enabled, HDR playback can switch to SDR while on battery. Some older Intel Mac models may also limit HDR playback resolution to 1080p, depending on the content and display. See Apple’s HDR video guidance for model and setting details.
Determine whether the appearance is specific to one app
If the desktop and other apps look normal but one editing or playback preview does not, treat it as an app-viewing issue rather than assuming the display itself is faulty. Tone mapping and preview controls can be application-specific.

Motion’s HDR canvas
In Apple Motion, HDR content is tone mapped in the canvas when shown on an HDR or SDR display. Motion’s XDR reference-mode workflow can turn off Show HDR as Tone Mapped. That option changes Motion’s view, not its final render, and should not be generalized to other Mac apps. Apple documents this behavior in the Motion guide to HDR canvas appearance.
Respond to a brightness-limited warning on an XDR display
This branch applies to a MacBook Pro with a Liquid Retina XDR display or a Pro Display XDR when Apple’s documented brightness-limited warning or state is present. Apple says high ambient temperature combined with extended bright-content use can limit brightness. Follow the steps for the affected system:

- Quit apps using significant system resources on a MacBook Pro.
- Use the Apple XDR Display or Pro Display XDR reference mode unless your workflow requires a different mode.
- Lower the room temperature and close or hide windows containing HDR content.
- Put the Mac to sleep and let the display cool for 5–10 minutes, then wake it. Apple Support’s instruction is: “Let your display cool down for 5–10 minutes, then press any key on the keyboard to wake your Mac.”
If the limitation continues at an ambient temperature below 77°F, Apple says service may be needed. These measures address the documented brightness-limited state; they are not a general cure for every HDR image that looks too bright. See Apple’s guidance for brightness limits on MacBook Pro and Pro Display XDR.
